(1) The mind must be calm and the sudden and unexpected mental stimulation must be quickly controlled for the most appropriate treatment. (2) Go to oncology specialists and seek for timely treatment and help from truly experienced cancer specialists. Special attention should be paid not to rush the treatment (except for emergencies, of course), but to do staging examination first, that is to say, to understand which organs of your whole body have already had tumor growth at present, because the treatment plan is different for different stages. (3) Enhance the determination to fight with cancer for a long time, set up the idea of “if it comes, then it will be safe”, stabilize emotions, enhance self-confidence, play the role of “cancer cure” in the mind, and actively cooperate with doctors.
